Description

Using the latest version of mingw64 and msys2, neither ruby 2.6.5 nor 2.7.0 compile.

The issue is with miniruby.exe - it gets built but does not work. For example:

$ ./miniruby.exe -v

Returns nothing (I assume it is crashing but its not triggering windows just in time debugger so hard to tell). Because of this, the various build rules that miniruby.exe execute do not work. For example, generating encdb.h from a template. The error is non-obvious:

./miniruby.exe -I./lib -I. -I.ext/common ./tool/generic_erb.rb -c -o encdb.h ./template/encdb.h.tmpl ./enc enc
make: *** [uncommon.mk:1070: encdb.h] Error 4198400

After experimentation, the problem is the inclusion of -pie in the link command to make miniruby.exe. This can be worked around by:

./configure --prefix=/ CPPFLAGS=-I/mingw64/include LDFLAGS=-L/mingw64/lib --enable-shared=yes --disable-pie

Note the inclusion of "--disable-pie".

Mingw has meant "mingw on cygwin", and msys has not been a supported platform.

I find that answer quite surprising. The RubyInstaller for windows is based on msys and mingw64 (and has been for many years):
